Set border for a specific marker in series in a Scatter Chart

[KLudvig]

Hi, for another question (#1247) there is a way to add fillColor to a specific marker like this:

series: [
  {
    name: 'Points',
    data: [
      {
        x: 1,
        y: 2.14
      },
      {
        x: 3.2,
        y: 5.8
      },
      {
        x: 3.8,
        y: 6.04,
        fillColor: '#111'
      },
      {
        x: 4.55,
        y: 6.77
      }
    ]
  }
]

Is there anyway to instead of fillColor add a border?
